You are going to build a new garage similar to the rectangular one you currently have. The current dimensions are 30 feet wide by 12 feet long. You need to stake and rope off where the concrete will be poured. If the new garage is going to have a width of 35 feet, how much rope are you going to need?

Respuesta :

Answer:

98 feet.

Step-by-step explanation:

The new garage is similar to the current one.

So if the new width is 35 feet the the new length, by proportion,  is:

= 12 * 35/30 = 14 feet.

So the length of the rope you'll need

= 2*35 + 2*14

= 70 + 28 = 98 feet.
